ICE RACK.

Application filed November 14, 1927. Serial No. 233,073.

This invention relates toa rack adapted for use in refrigerators to hold ice in the ice compartments thereof. It is a primary object and purpose of the present invention to construct a rack of great strength, rigidity and durability, reinforcing and adding to the strength where it is most needed and making the same entirely from a single piece of sheet metal whereby economy in manufacture as well as the advantages of strength,

rigidity and durability are secured.

An understanding of the invention may be had from following description taken in connect-ion with the accompanying drawing, in

which,

Fig. 1 is a perspective view of the ice rack of my invention.

Fig. 2 is a transverse vertical section therethrough.

Fig. 3 is a fragmentary longitudinal section substantially on the plane of line 3-3 of Fig. 1.

Fig. 4 is a similar view on line 4-4 of Fig. 1, and

Figs. 5 and 6 are sections on the planes of lines 5 5 of Fig. 3 and 6-6 of Fig. 4, respectively.

the plane of Like reference characters refer to like parts in the different figures of the drawing.

The ice rack is made from a single plate of sheet metal and includes two sections 1 and 2 corrugated lengthwise to increase the strength and rigidity thereof. Located at the center of the rack and between the sections 1 and 2 is a substantially elliptical shaped section 3 of concave form at its upper side, around which is a groove 4, the metal being pressed downwardly between the edges of the section 3 and the inner adjacent portions of the sections 1 and 2. At each end of the section 3 beyond the groove 4 is a relatively narrow plane portion 5 terminating a short distance from the end of the rack, the metal being cut from the inner edges of each of the sections 1 and 2 and bent downwardly at right angles to make legs 6 which at their lower ends are bent inwardly making the inturned horizontal feet 7. For the purpose of strengthening and reinforcing the corners where the legs 6 join the said sections 5 the metal at each side edge is pressed inwardly to provide flanges 8, one at each side of each corner.

At the outer side edge of each of the corrugated sections 1 and 2 the metal is plain and uncorrugated making a flat side section 9 lying in the same plane with the flat top portions 5 previously described. Each section 9 at each end likewise terminates short of the ends of the adjacent corrugated sections 1 and 2 of lthe rack and the metal is cut from said adjacent corrugated sections, turned downwardly at right angles as indicated at 10 and then inwardly at right angles to make the feet 11.

The outer sections 9 with their supporting legs 10 preferably are greatly strengthened and reinforced by bending the metal inwardly at 11 underneath each section 9 against each leg 10 and over each foot 11. That is, underlying each section 9 and connected thereto by the bend 11 is a reinforcing section 13 of metal of the same thickness and integral with the remainder of the rack. Likewise each leg 10 has an inner part 14 turned to lie snugly thereagainst and each foot 11 is covered by a part 15 as shown.

The corners are greatly strengthened and reinforced by means of the following structure: The corner 16 between a section 9 and a leg 10 is made by bending the same in the arc of a circle while the corner 17 between the parts 13 and 14 located inside of section 9 and leg 10 is bent on an arc of a greater radius, so that there is a space between the corners 15 and 17 as shown in Fig. 3. This space is enclosed by sides 18 and 19 extending from the corner portion 16 to the corner portion 17 as shown in Figs. 1 and 5. This adds to a very great degree to the strength and rigidity of the rack and reinforces and strengthens the same at the points where it is most needed.

The invention as previously stated permits the manufacture of ice racks from a single plate of sheet metal with the use of proper dies, and makes a rack which is exceptionally strong and durable and one which can be manufactured in large quantities at low cost. The rack also has an attractive appearance. The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.

I claim:

1. An ice rack formed from a single plate of sheet metal and including parallel corrugated sections connected by an intermediate section, and including at the outer edges of said corrugated sections plain sections, each of said plain sections and said intermediate section at each end thereof having a leg bent downwardly and then turned at right angles to form a supporting foot, all of the supporting feet being located in the saine horizontal plane.

2. An ice rack formedfrorn a single plate of sheet metal corrugated lengthwise thereof and having at each outer edge a plain uncorrugated section, each of said plain sections at each end thereof having a short length cut from the adjacent metal and bent downwardly at right angles and terminating at its lower end in a horizontally positioned foot, all of said feet being in the same horizontal plane.

3. An ice rack comprising a plate of sheet metal longitudinally corrugated and having plain uncorrugated sections at the opposite side edges, each of said sections at each end being equipped with a downturned supporting leg and each of said sections and each of said legs being strengthened and reinforced by integral metal parts lying against the inner sides thereof.

4. A construction as defined in claim 3, with an intermediate portion of the plate uncorrugated and at each end having a leg turned downwardly therefrom.

5. An ice raclr made from a single plate of sheet metal corrugated for strength and having a plain uncorrugated section at opposed side edges, each of said plain sections at each end having a leg turned to extend downwardly, said plain sections and legs being continued outwardly and then bent to lie against the inner sides of said sec-A tions and legs, the radiusfof curvature between said sections and legs being less than the radius of curvature between. the parts lying against the inner sides thereof, whereby the corners between the supporting legs and the remainder of the rack are strengthened and reinforced. Y

6. A construction as defined in claim 5, provided with an intermediate section between the side edges of the rack, legsturned downwardly from each end thereof and flanges pressed inwardly at the corners between said intermediate section and the legs connected thereto for the purpose described.

7 An ice rack formed from a single plate of sheet metal including, corrugated sections between which isva convex section with a groove around the same between its edges and the adjacent portions of the plate, and supporting legs slit from the plate at each corner and adjacent each end of the inter` mediate convex section extending downwardly and having inturned lower ends comprising supporting feet all located in the same horizontal plane. V

8. An ice rack formed of a single piece of sheet metal having a dome integrally formed at its central portion, the upper surface of said dome being substantially flush with the upper surface of the body of the rack and the periphery of the dome extending below the under surface of the rack.

9. An ice rack Vformed of a. single piece of sheet metal, the main body of which is corrugated and the central portion being uncorrugated and formed in the shape of a dome, the upper surface of the dome being substantially flush with the upper surface of the rack and the periphery of the dome deplnding below the lower surface of the rac 10. An ice rack formed of a single piece of sheet'inetal having a dome integrally formed at its central portion, the upper surface of said dome being substantially flush with the upper surface of the body of the rack and the periphery of the dome extending below the under surface of the rack, and legs to support the raclrin elevated position.

1l. An ice rack formed of a single piece of sheet metal having a dome integrally formed at its central portion, the upper surface of said dome being substantially flush with the upper surface of the body of the rack and the periphery of the dome extending below the under surface of the rack, and integrally formed legs on the body of the rack to support it in elevated position.

l2. An ice rack formed of a single piece of sheet metal, the main body of which is corrugated and the central portion being uncorrugated and formed in the shape of a dome, the upper surface of the dome being substantially flush with vthe upper surface of the rack and the periphery of the dome depending below the lower surface of the raclr, and legs to support the rack in elevated position.
